BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a first-aid device, and more specifically to a first-aid device for detecting myocardial infarction employing a wearable textile put on a user to carry a first detection alarm unit for actively detecting myocardial infarction, providing the user medicine to alleviate painful symptom through a charging first-aid unit connected to the first detection alarm unit, and charging a second detection alarm unit as a spare part through the first detection alarm unit.

2. The Prior Arts

As well known, most people prefer meat and greasy food with heavy salt, and are obviously lack of vegetable and fruit, particularly without doing elementary exercise, and consequently, some lethal cardiovascular disease like arteriosclerosis, aortic dissection, cerebral stroke, or myocardial infarction possibly develops, even results in sudden death and causes serious loss of family and society.

Generally, the patient once suffering from cardiovascular disease will lose 10% chance of survival from well therapy if one minute delays for first-aid. And, if first-aid is delayed over 5 minutes, serious damage of the body is permanent and not cured. Thus, it is crucial to take first-aid as soon as possible.

As with myocardial infarction, the coronary artery supplying nutrient and oxygen to the heart may become narrow and retard blood flow because of smoking, high blood pressure, and high blood lipid. Once the coronary artery is blocked to cause the blood flowrate to reduce to a serious level, the patient will suffer from chest distress, chest pain, cold sweat, angina pectoris, or even myocardial infarction. In particular, acute and lethal myocardial infarction often happens when the environmental temperature quickly drops, or after the patient did too excessive exercise or immersing in a warm bath too long. At this time, if the patient takes one sublingual tablet like nitroglycerin, the blood vessel immediately expands to alleviate the level of myocardial infarction and avoid completely ceasing the blood flow to the heart. Thus, the heart can temporarily keep normal function, and the patient acquires enough time for first-aid while delivered to the hospital.

Commonly, the sublingual tablet takes effect after one to three minutes, and the patient should relieve from myocardial infarction after five minutes at most. Therefore, the patient may take one sublingual tablet every five minutes before delivered to the hospital, but totally three sublingual tablets are the maximum. To assure the effect of the medicine, it is recommended to readily carry the sublingual tablets in a brown medicine bottle, like putting in the pocket of the clothes or carry-on bag. However, it is not appropriate to put the sublingual tablets in the pocket closely attached to patient's body because body temperature deteriorates the effect of the medicine.

From the above mention, the patient should first correctly judge and identify by himself or herself that myocardial infarction happens, and then immediately take off the sublingual tablet from the medicine bottle and quickly keep it under the tongue in the mouth for gradually releasing. However, when the patient just did excessive exercise and felt tired, or suffers from headache or pain due to bad sleep, cold, dyspepsia, apepsia, or ulcer, the judgement is possibly biased and myocardial infarction is identified as other disease, unfortunately losing the chance of taking the medicine for first-aid in time.

In addition, when the patient fails to take off the medicine and clearly tell people the location of the medicine, no one can help the patient to relief the syndrome, and it is the only way to call the ambulance. Consequently, the patient may suffer from serious and permanent syndrome, and not recover, even death.

Therefore, it is greatly needed to provide a first-aid device for detecting myocardial infarction employing a wearable textile put on a user to carry a first detection alarm unit for actively detecting myocardial infarction, providing the user medicine to alleviate painful symptom through a charging first-aid unit connected to the first detection alarm unit, and charging a second detection alarm unit as a spare part through the first detection alarm unit, thereby overcoming the problems in the prior arts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

Please refer to FIG. 1, showing a first-aid device for detecting myocardial infarction according to the embodiment of the present invention. As shown in FIG. 1, the first-aid device for detecting myocardial infarction of the present invention generally comprises a wearable textile 10, a first detection alarm unit 20A, a second detection alarm unit 20B, and a charging first-aid unit 30 for actively detecting and alarming myocardial infarction, instantly supplying crucial medicine, and providing a function of charging so as to prevent the patient suffering from myocardial infarction from sudden death due to no first-aid, and further acquiring precious time for subsequent treatment.

Specifically, the wearable textile 10 like comfortable underwear with appropriate resilience is put on a user or patient, and the first detection alarm unit 20A is provided on the wearable textile 10, serves as an operating detection alarm unit, and keeps in an operation status. Additionally, the second detection alarm unit 20B serves as a spare detection alarm unit, remains in a standby status, and is accommodated in and charged by the charging first-aid unit 30.

The wearable textile 10 is provided with a plurality of sensing electrodes 12, a plurality of conductive connections 14, and a connection slot 16. Each of the conductive connections 14 is connected to the corresponding sensing electrode 12 and the connection slot 16, and the sensing electrodes 12 are preferably provided on the chest of the user like the place around the heart for sensing and transferring a physiological signal like Electrocardiogram (ECG) to the connection slot 16 through the conductive connections 14. In general, the present invention needs at least five sensing electrodes 12 to acquire the physiological signal with sufficient preciseness.

Further, the sensing electrodes 12, the conductive connections 14, and the connection slot 16 are specifically provided on the inside of the wearable textile 10 such that the sensing electrodes 12 are well attached onto the body of the user after the user puts on the wearable textile 10 to easily sense the physiological signal, and the sensing electrodes 12, the conductive connections 14, and the connection slot 16 are not exposed outside to keep aesthetic. In addition, the connection slot 16 can be designed to be exposed outside for the user to easily and readily remove or insert the first detection alarm unit 20A.

The first detection alarm unit 20A and the second detection alarm unit 20B are implemented with the same electric function, and one difference between the first detection alarm unit 20A and the second detection alarm unit 20B is that the first detection alarm unit 20A has sufficient power and is connected to the connection slot 16 of the wearable textile 10 for normal operation, and the second detection alarm unit 20B is insufficient in power and charged by the charging first-aid unit 30. Thus, only the first detection alarm unit 20A is explained in detail for technical aspects in the following description.

Further refer to FIG. 2. The first detection alarm unit 20A comprises a connection port 21 for connecting the connection slot 16 in a detachable manner to receive the physiological signal, generate and transfer an emergency alarm signal based on the physiological signal, and at the same time, perform an alarm operation. Moreover, the first detection alarm unit 20A comprises a charging port 22 a controller 23, an alarm 24, and a rechargeable battery 25. The rechargeable battery 25 supplies power to the controller 23 and the alarm 24 for operation. The controller 23 is electrically connected to the charging port 22 and the alarm 24, receives the physiological signal, and determines if the user suffers from myocardial infarction based on the physiological signal. The controller 23 generates and transfers the emergency alarm signal when the user suffers from myocardial infarction. The alarm 24 receives the emergency alarm signal and performs the alarm operation based on the emergency alarm signal. In addition, the emergency alarm signal is received by a remote processing unit 40 for an operator of the remote processing unit 40 to perform an emergency treatment so as to assist the user suffering from myocardial infarction. For instance, the first detection alarm unit 20A transmits the emergency alarm signal through a 5G wireless communication channel, and the emergency treatment of the remote processing unit 40 comprises calling an ambulance or at least one medical personnel of arriving on a location of the user for performing first-aid.

Furthermore, the first detection alarm unit 20A stores and transfers the physiological signal to the remote processing unit 40 for detailed examination and analysis.

Each of the first detection alarm unit 20A and the second detection alarm unit 20B comprises a battery status indicating light (not shown) to indicate that the rechargeable battery 25 is in a charging status, a charging complete status, or a power insufficiency status. Specifically, battery status indicating light is intended to inform or remind the user that the first detection alarm unit 20A is insufficient in power and it needs to remove the first detection alarm unit 20A from the connection port 16 of the wearable textile 10 and further place the first detection alarm unit 20A in the charging first-aid unit 30 for charging. When the first detection alarm unit 20A is in charging complete status, the first detection alarm unit 20A is inserted into the connection port 16 of the wearable textile 10 for normal use.

Preferably, the user can easily and readily carries the charging first-aid unit 30 for use like putting the charging first-aid unit 30 in the pocket of the clothes, trousers, or skirt, or the hand-carry bag. More specifically, the charging first-aid unit 30 comprises a charging space 31 and a medicine box 33, and the charging space 31 comprises a charging slot 31A. The second detection alarm unit 20B is accommodated in the charging space 31 for charging, and the medicine box 33 accommodates at least one sublingual tablet P like nitroglycerin sublingual tablet for urgently expanding the blood vessels and lasting for 30 minutes.

Preferably, the user can easily and readily carries the charging first-aid unit 30 for use like putting the charging first-aid unit 30 in the pocket of the clothes, trousers, or skirt, or the hand-carry bag. More specifically, the charging first-aid unit 30 comprises a charging space 31 and a medicine box 33, and the charging space 31 comprises a charging slot 31A. The second detection alarm unit 20B is accommodated in the charging space 31 for charging, and the medicine box 33 accommodates at least one sublingual tablet P like nitroglycerin sublingual tablet for urgently expanding the blood vessels and lasting for 30 minutes.

One primary function provided by the above alarm 24 is to employ the alarm operation to alarm or remind the user of instantly opening the medicine box 33 and taking the sublingual tablet P. The alarm operation comprises generating a specific sound, vibration, or light signal. For instance, the sound comprises a piece of voice like “myocardial infarction, please take the sublingual tablet right now”, which also informs or reminds some people around the user of helping open the medicine box 33 and take off the sublingual tablet P for the user to take, thereby winning for some precious time for first-aid and preventing the heart from sudden cardiac arrest or permanent damage due to insufficient blood supply.

Further, in another detachable manner, the charging port 22 of the second detection alarm unit 20B is electrically connected to the charging slot 31A of the charging space 31 of the charging first-aid unit 30 for charging.

More specifically, the charging first-aid unit 30 comprises a charge controller 34 and a rechargeable battery module 35. The charge controller 34 is provided with a universal serial bus (USB) input port 34A for connecting an external power source PWR, and a power output port 34B for connecting the charging slot 31A. The charge controller 34 is connected to the rechargeable battery module 35 for charging the rechargeable battery module 35 by an external power from the external power source PWR through the USB input port 34A, and the charge controller 34 outputs an output power from the rechargeable battery module 35 to the charging slot 31A through the power output port 34B.

Moreover, the charging first-aid unit 30 further comprises a wireless communication unit 36 for linking to the first detection alarm unit 20A in a wireless manner like blue tooth, Zigbee or WiFi to sustain a communication operation. The first detection alarm unit 20A employs the communication operation to determine if a distance between the first detection alarm unit 20A and the charging first-aid unit 30 is larger than an upper threshold. If the distance is larger than the upper threshold, the first detection alarm unit 20A generates an alarm sound, an alarm vibration, or an alarm light signal to instantly inform of the user that the charging first-aid unit 30 is not within the preset safety range. At this time, the user does not bring with the charging first-aid unit 30, possibly carelessly leaving it somewhere, and it is necessary to bring back the charging first-aid unit 30, otherwise the user perhaps loses the chance of taking the sublingual tablet P for first-aid once suffering from myocardial infarction.

From the above mention, one feature of the present invention is that the wearable textile is put on a user and carries the first detection alarm unit for actively and ceaselessly detecting myocardial infarction to avoid erroneous judgement and losing precious time for first-aid, and the user easily carries and readily employs the charging first-aid unit to provide the crucial medicine to alleviate painful symptom so as to prolong the first-aid time and increase the chance of arriving at the hospital for well therapy.

In particular, when the user suffers from myocardial infarction, loses consciousness, or does not speak clearly to ask some people for help, the first detection alarm unit actively generates sound, vibration, or light signal to inform some people of taking of the medicine from the charging first-aid unit for the user to take, thereby greatly increasing the chance of cure.

Another feature of the present invention is that the charging first-aid unit provides the function of charging and accommodating the second detection alarm unit as a spare part. Thus, when the first detection alarm unit is insufficient in power, the first detection alarm unit is readily taken off and instantly replaced by the second detection alarm unit. Then, the charging first-aid unit charges the first detection alarm unit. Thus, the function of ceaseless detection and first-aid is implemented. In other words, the first detection alarm unit and the second detection alarm unit are alternatively employed to assure the user suffering from myocardial infarction to acquire the chance of first aid.
